Perfect Host

After the dust has settled, the sun has set. Everything is resolved. Shepard throws a party to celebrate his win. For this achievement all you have to do is throw the party. Go back to the citadel and purchase party supplies, then head back home and initiate party mode [ON] OFF.... After the party is over, "ding" achievement unlocked.

Video walkthrough of the party on Insanity diffculty (lol) coming soon....
